Sentiment indicators are meant to demonstrate how a group of investors and traders feel about the markets.

This group might be “dumb money”, which suggests that you should trade opposite to what the prevailing sentiment is.

This group might be “smart money”, which suggests that you should trade according to what the prevailing sentiment is.

The majority of sentiment indicators are “dumb money” sentiment indicators. These indicators become “optimistic” after the market goes up and “pessimistic” after the market does down. Hence, these are essentially used as contrarian indicators.

We’ve already said that sentiment indicators aren’t the best. But if you’re still interested in them, here are some common sentiment indicators for the stock market and other financial markets.

Stock market sentiment indicators

The VIX (volatility index) is the most commonly used sentiment indicator for the stock market. VIX is essentially a “fear index”.

It rises when the majority of investors and traders are more pessimistic and expect higher volatility in the stock market.

It falls when the majority of investors and traders are optimistic and expect lower volatility in the stock market.

In other words, VIX tends to move inversely with the S&P 500 over the short-medium term.

VIX is based on options. VIX tends to swing within a range over the long run. It bottoms at around 10 and it rarely goes above 40.

This is a price-based sentiment indicator for the U.S. stock market. This is used as a “dumb money” contrarian indicator.
